NAME

       rsbackup-snapshot-hook - rsync-based backup utility

SYNOPSIS

       rsbackup-snapshot-hook [OPTIONS]

DESCRIPTION

       rsbackup-snapshot-hook  creates  and  removes LVM snapshots when configured as a pre- or post-backup-hook
       for rsbackup(1).

       Snapshots will only be created for volumes that have a corresponding directory in the snapshot directory.
       For  instance,  a  snapshot  will  be created for the volume root if /snap/root exists.  (Use the --snaps
       option to change the snapshot directory.)  Such volumes must be stored in a logical volume.

       Leftover snapshots are always unmounted and removed before creation.

       Snapshots are given only a fraction of the size of the original volume.   Use  the  --divisor  to  change
       this.

       After creation snapshots are fsck'd and mounted.  If an error occurs in any part of the creation process,
       the partially snapshot created snapshot may be left in place (and ultimately be torn down when the  post-
       backup-hook is run).

OPTIONS

       --snaps, -s PATH
              Set the path to the snapshot directory.  The default is /snap.

       --divisor, -d DIVISOR
              Set the snapshot size ratio.  The default is 5.

       --help, -h
              Display usage message.

       --version, -V
              Display version string.
